HIV infection and reproductive health in teenage women orphaned and made vulnerable by AIDS in Zimbabwe

Targeting AIDS orphans and child-headed households? A perspective from national surveys in South Africa, 1995-2005

In the HIV and AIDS sphere, children remain on the margins with respect to advocacy, prevention, treatment and care. Moreover, concern is generally limited to specific categories of children, most especially children living with HIV, orphaned children and child-headed households. Excluded from view are the very large numbers of children affected by generalized HIV/AIDS epidemics, now in advanced stages, in already impoverished countries in southern Africa. In this paper, we use information from comparable national household surveys in South Africa, in five waves between 1995 and 2005, to examine the impact of HIV and AIDS on children and on the structure of the households in which they find themselves. The question posed is whether it is appropriate to target orphans and child-headed households in this context. The data indicate that orphaning, particularly loss of a mother, tripled during this period, as is to be expected from rising adult mortality. Though they remain a small proportion, child-only households also rose markedly during this time. However, difficult as their situation is, neither orphans nor child-only households appear to be the worst-off children, at least from the point of view of reported sources of financial support and per capita monthly expenditure. Households headed by single adults and young adults are economically vulnerable groups not yet included in efforts to support affected children and families. Poverty is a pitiless backdrop to the AIDS epidemic and needs to be at the heart of strategies to address the needs of all vulnerable children in hard-hit communities.

Maternal versus paternal orphans and HIV/STI risk among adolescent girls in Zimbabwe

The AIDS epidemic has contributed to a drastic increase in the number of orphans in Zimbabwe. Orphans (whether orphaned by AIDS or other causes) have been shown to have economic and educational disadvantages as well as poor reproductive health outcomes. We recruited a convenience sample of 200 girls in a peri-urban area of Zimbabwe to examine the impact of orphan status (compared to non-orphans) on household composition, education, risk behaviour, pregnancy and prevalent HIV and HSV-2 infection. In our population, maternal orphans were more likely to be in households headed by themselves or a sibling, to be sexually active, to have had an STI, to have been pregnant and to be infected with HIV. Paternal orphans were more likely to have ever been homeless and to be out of school. Our findings suggest that maternal care and support is important for HIV prevention. This finding corroborates previous research in Zimbabwe and has implications for intervention strategies among orphan girls.

A systematic review on the meaning of the concept 'AIDS Orphan': confusion over definitions and implications for care

Global publications on the international AIDS epidemic report on the existence of an ever-increasing number of orphans and vulnerable children. It has been suggested that by the end of this decade there will be in excess of 25 million AIDS orphans globally, an issue which will require understanding and organisation of long-term medical, psychological and social support. This study provides a systematic review to examine the use, overuse and misuse of the term orphan and explores the benefits and limitations of this approach. It then summarises the knowledge on orphans to date. Using a search strategy of published studies and recent conference abstracts, 383 papers were identified where the concept of AIDS and Orphan was raised. The papers were systematically coded and reviewed to understand when and how a child is labelled an orphan, and to summarise the effect of orphanhood on outcome measures, most notably psychologically and physically. All controlled studies published prior to 2006 were reviewed. A consistent picture of negative effects of parental death (however defined) on a wide range of physical, socioeconomic and psychological outcomes were recorded. Seventeen studies met criteria for in-depth review (empirical, fully published, control group). The majority of studies are cross-sectional (two are longitudinal) and employ a very wide array of measures - both standardised and study specific. This detailed analysis shows a mixed picture on outcome. Although most studies report some negative effects, there are often no differences and some evidence of protective effects from quality of subsequent care and economic assistance. The lack of consistent measures and the blurring of definitions are stumbling blocks in this area.

A developmental psychopathology framework of the psychosocial needs of children orphaned by HIV

In addition to the obstacles to a successful resolution of grief normally faced by children whose parents have died, children orphaned by AIDS may face additional psychological and social challenges. However, limited attention has been paid to psychosocial and developmental needs of children orphaned by HIV/AIDS, particularly in resource-poor countries or regions. In this article the authors review the global literature on child bereavement and AIDS orphan care experiences in developing countries and present a developmental psychopathology model of the psychosocial issues facing AIDS orphans. The authors identify gaps in the literature and provide suggestions for future research on AIDS orphans in resource-poor countries and regions. They emphasize that future studies need to assess the status of behaviors and mental health of children orphaned by AIDS within a developmental framework, identify those individual and social factors associated with grief, and examine the long-term impact of quality of care, developmental maturation, and attachment with caregivers on the psychosocial well-being of AIDS orphans.

From affected to infected? Orphanhood and HIV risk among female adolescents in urban Zimbabwe

BACKGROUND

Despite the 15 million children orphaned by AIDS, and fears of sexual vulnerability, little is known about the link between orphanhood and HIV risk.

METHODS

A random sample of 1283 15 to 19-year-old girls in a high-density suburb of Harare was identified in a cross-sectional survey in 2004. A total of 863 agreed to be interviewed and 839 provided a specimen for HIV and herpes simplex virus type-2 (HSV-2) testing. Sexual health outcomes, sexual behaviours and marriage were assessed by type and timing of orphanhood.

RESULTS

Half of the participants were single or double orphans. Prevalence of HIV and/or HSV-2 was higher among orphans than non-orphans [17 versus 12%; age-adjusted odds ratio (aOR) = 1.5; 95% confidence interval (CI) 1.0-2.3]. Associations with orphan status were only significant among the 743 never-married participants. In comparison with non-orphaned peers, increased sexual risk (defined as HSV2-positive, HIV-positive or ever pregnant) was seen among maternal orphans (aOR = 3.6; 95% CI, 1.7-7.8), double orphans (aOR = 2.4; 95% CI, 1.2-4.9), and girls who lost their father before age 12 (aOR = 2.1; 95% CI, 0.9-4.8) but not later (aOR = 0.8; 95% CI, 0.3-2.2). Maternal and double orphans were most likely to initiate sex early and to have had multiple partners. Maternal orphans were least likely to have used a condom at first sex, and to have a regular sexual partner. Experience of forced sex was high in all groups.

CONCLUSIONS

In urban Zimbabwe, female adolescent orphans are at increased risk of HIV and HSV-2 infection. Infection rates vary by type and age of orphanhood, and marital status, and are associated with high-risk sexual behaviours.

When did HIV incidence peak in Harare, Zimbabwe? Back-calculation from mortality statistics

HIV prevalence has recently begun to decline in Zimbabwe, a result of both high levels of AIDS mortality and a reduction in incident infections. An important component in understanding the dynamics in HIV prevalence is knowledge of past trends in incidence, such as when incidence peaked and at what level. However, empirical measurements of incidence over an extended time period are not available from Zimbabwe or elsewhere in sub-Saharan Africa. Using mortality data, we use a back-calculation technique to reconstruct historic trends in incidence. From AIDS mortality data, extracted from death registration in Harare, together with an estimate of survival post-infection, HIV incidence trends were reconstructed that would give rise to the observed patterns of AIDS mortality. Models were fitted assuming three parametric forms of the incidence curve and under nine different assumptions regarding combinations of trends in non-AIDS mortality and patterns of survival post-infection with HIV. HIV prevalence was forward-projected from the fitted incidence and mortality curves. Models that constrained the incidence pattern to a cubic spline function were flexible and produced well-fitting, realistic patterns of incidence. In models assuming constant levels of non-AIDS mortality, annual incidence peaked between 4 and 5% between 1988 and 1990. Under other assumptions the peak level ranged from 3 to 8% per annum. However, scenarios assuming increasing levels of non-AIDS mortality resulted in implausibly low estimates of peak prevalence (11%), whereas models with decreasing underlying crude mortality could be consistent with the prevalence and mortality data. HIV incidence is most likely to have peaked in Harare between 1988 and 1990, which may have preceded the peak elsewhere in Zimbabwe. This finding, considered alongside the timing and location of HIV prevention activities, will give insight into the decline of HIV prevalence in Zimbabwe.

HIV-associated orphanhood and children's psychosocial distress: theoretical framework tested with data from Zimbabwe

OBJECTIVES

We measured the psychosocial effect of orphanhood in a sub-Saharan African population and evaluated a new framework for understanding the causes and consequences of psychosocial distress among orphans and other vulnerable children.

METHODS

The framework was evaluated using data from 5321 children aged 12 to 17 years who were interviewed in a 2004 national survey in Zimbabwe. We constructed a measure of psychosocial distress using principle components analysis. We used regression analyses to obtain standardized parameter estimates of psychosocial distress and odds ratios of early sexual activity.

RESULTS

Orphans had more psychosocial distress than did nonorphans. For both genders, paternal, maternal, and double orphans exhibited more-severe distress than did nonorphaned, nonvulnerable children. Orphanhood remained associated with psychosocial distress after we controlled for differences in more-proximate determinants. Maternal and paternal orphans were significantly more likely than were nonorphaned, nonvulnerable children to have engaged in sexual activity. These differences were reduced after we controlled for psychosocial distress.

CONCLUSIONS

Orphaned adolescents in Zimbabwe suffer greater psychosocial distress than do nonorphaned, nonvulnerable children, which may lead to increased likelihood of early onset of sexual intercourse and HIV infection. The effect of strategies to provide psychosocial support should be evaluated scientifically.

Moving from preventing HIV/AIDS in its infancy to preventing family illness and death (PFID)

In April 2007, UNAIDS released Securing the future--advocating for children, a call for the global community to recognize that "children still remain largely absent from national and international political responses to the AIDS pandemic". Most efforts to date to protect children from HIV have focused on prevention of mother-to-child transmission (PMTCT) programs. Though expanding PMTCT programs, particularly in sub-Saharan Africa, are crucial, even widespread PMTCT programs would still be grossly inadequate for achieving the goal of protecting children from HIV/AIDS. The global community needs to fundamentally reframe its approach to HIV prevention to fully address the health of families, otherwise the future for at-risk children is likely to remain bleak. After identifying challenges with current approaches, we review recent research that provides insights into ways prevention programs may be adapted to better protect families and children from the devastating consequences of HIV/AIDS. Only by protecting families from HIV/AIDS will we be able to achieve the goal of an AIDS-free generation.

HIV incidence and poverty in Manicaland, Zimbabwe: is HIV becoming a disease of the poor?

BACKGROUND

In Zimbabwe, socioeconomic development has a complicated and changeable relationship with HIV infection. Longitudinal data are needed to disentangle the cyclical effects of poverty and HIV as well as to separate historical patterns from contemporary trends of infection.

METHODS

We analysed a large population-based cohort in eastern Zimbabwe. The wealth index was measured at baseline on the basis of household asset ownership. The associations of the wealth index with HIV incidence and mortality, sexual risk behaviour, and sexual mixing patterns were analysed.

RESULTS

The largest decreases in HIV prevalence were in the top third of the wealth index distribution (tercile) in both men at 25% and women at 21%. In men, HIV incidence was significantly lower in the top wealth index tercile (15.4 per 1000 person-years) compared with the lowest tercile (27.4 per 1000 person-years), especially among young men. Mortality rates were significantly lower in both men and women of higher wealth index. Men of higher wealth index reported more sexual partners, but were also more likely to use condoms. Better-off women reported fewer partners and were less likely to engage in transactional sex. Partnership data suggests increasing like-with-like mixing in higher wealth groups resulting in the reduced probability of serodiscordant couples.

CONCLUSION

HIV incidence and mortality, and perhaps sexual risk, are lower in higher socioeconomic groups. Reduced vulnerability to infection, led by the relatively well off, is a positive trend, but in the absence of analogous developments in vulnerable groups, HIV threatens to become a disease of the poor.

Sexual risk behavior among South African adolescents: is orphan status a factor?

There is concern that orphans may be at particular risk of HIV infection due to earlier age of sexual onset and higher likelihood of sexual exploitation or abuse; however, there is limited empirical evidence examining this phenomenon. Utilizing data from 1,694 Black South African youth aged 14-18, of whom 31% are classified as orphaned, this analysis explores the relationship between orphan status and sexual risk. The analysis found both male and female orphans significantly more likely to have engaged in sex as compared to non-orphans (49% vs. 39%). After adjusting for socio-demographic variables, orphans were nearly one and half times more likely than non-orphans to have had sex. Among sexually active youth, orphans reported younger age of sexual intercourse with 23% of orphans having had sex by age 13 or younger compared to 15% of non-orphans. Programmatic implications of these findings for the care and protection of orphans are discussed.
